This invention relates to'improvements in feeding mechanism for paper sheets, for feeding the sheetsto a printing press.

It is the object of this invention to provide an improved feeding table for use in connection with a paper feeding mechanism for feeding sheets of paper to a printing press.

It is particularly the object of thisinvention-to provide 'a receiving table on which there are means for aligning the sheets of paper and maintaining thesheets in a posi-' tion to be fed to a printing press.

These and other objects and advantages.

will appear from the following'description taken in connection with the drawings This application is a division of application Ser. No. 470,824, filed July'26, 1930.

I Referring to the drawingsi f Figure 1 is a top plan view of the receiving table shown in connection with a print- 2 ing press.

Figure 2 is asfront elevation of the printing press with the associated feeding means. Figure 8 is a fragmentary view of the rear guide for a stack of sheets o'fpaper.

Figure 4 is a View at right angles'to Figure 3. Figure 5 is a perspective View of the feeder bar clamp.

The feeding table is shown in connection 7 with a suction-operated feeding means for delivering sheets of paper, one at a time, from p In order to support the stack ofsheets of paper there is 5 provided a platform 1, from which there-e5;-

tends upwardly a plurality of feed table guides 2. These guides engage thefeed table 3 and guide it in its vertical movement.

For moving the table up and down in a vertical direction there extends downwardly' from the table through the platform aplurality of feeder racks 4, which are engaged.

by suitable operating gear located beneath the platform. The operation of the racks 4 for the elevation of the feed table is no part Therefore, the racks are not further described. I

Supported" on eachside of the platform and extending upwardly inthe form of loop or bow there is a feeder bar 5. This fingers 7 a. This reari'guide isin'the' form of]. 'aV with the open end downward, and en'-' gages the edge-of 'astackof paper located on s top of the feed'table.

supported on each side of the platform is the platform.

1 bar enter-Ids upwardly from each .side the platform. and across the top of the platform,

and over the: feed table, as: clearly: shown in F'igure 2. The horizontal part of the'guide stance there are two of thesere'ar guide bars, each of whlch has on one end rear guide p v These rearguides-may be arranged loi'i'gitudinally of the guide bar and they may be arranged or adjustedtrans- I versely of the bar, thereby accommodating sheets of different"lengthsand-different ---widthsw v Y The-sheets are fedbymean's ofsuctio n tubes; and in order that the, sheets may be easily fed'there is provided adjacent the stack of' sheets a plurality offlutter nozzles '8, connectedto'tubes'9 which lead to some suitable source of air pressure; Suitably 'a' feeder arm-.10, which has" on its" upper or outer end a feeder bar or frame 1 -1'. This frame or bar 11 has a plurality of shoes-12, eachof which is supported by a shoe holder 13. Each feeder shoe hasconnected thereto an: air-tube 14' through which air is delivered to the' shoes,"or throughwhich a'ir is drawn for'taking up a sheet "of 'paper' on top of the pile for deliveryto the printing; press. Theends 'ofthe feeder arms'fremote'from thearmshaft-l5, suitably supported adjacent shaft j I jWhen it is desired that a strip-of paper f 'be removed from the stack the feeder shoes are brought to 'the 'top' of the stack,- suction is produced in the shoes, wherebyaYs he'et of paper ispicked up and by a swinging movement a of the feeder 1 arms} the sheet of paper is transferred to a; transfer table 16,

where it is releasedfor transmission to the' press for printing-purposes.- aThe=printing T f 'I'nechanismis: no- 'partofth s t li' e tion After thesheetofpaper hasbeen print- 19 y as frame-11*. are 'pivotally attached to a' feeder V The; arms 10 swingwith the r ed it is again removed to a delivery table 17. Suitably supported by some part of the printing mechanism there are brackets 19 which support a transverse supporting rod 18.

Extending from the brackets 19 in the present instance two in number, are fingers 20, onefrom each bracket. On each finger is a longitudinal guide 21, adjustably supported on'the finger 20. There is also on each finger 20 a rear aligning guide 22, which extends partly across and above the table for properly aligning sheets of paper transferred to the receiving table. There is also extending from the rod 18 an arm 23.

This arm has thereon a separator 24 used for separating the sheets into two different stacks as they are fed to the receiving table. This separator is used when two sheets at a time are being fed from the feeding tablefor printing purposes. The apparatus is adapted to feed one or two sheets of paper, depending upon the adjustment. This separator will separate sheets into two different piles. the arm extending across the table slightly above the table with the separator extending from the arm toward the top of the table. The stack of sheets of paper located on the feeding table for delivery to the feeding press is indicated by the numeral 25. There may be one or more of these stacks of sheets of paper, depending upon whether one or two sheets are being printed at a time.

I desire to comprehend within my invention such modifications as may be embraced within my claims and the scope of my invention.

Having thus fully described my invention,

7 what Iclaim as new and desire to secure by Letters Patent, is:

1. In combination, a feeder table adapted to support a plurality of stacks of sheets, an arch member carried by said table arranged over and transversely of said sheets, supporting clamp members mounted over the stacks of said sheets adjustably on said arch, transversely adjustable members carried thereby, and adjustable depending fingers supported by each transversely adjustable member engaging the backs of the stacks of said sheets.

2. In a printing press, a feeder table, an arch member extending transversely over the table,a plurality of guide bars supported by the arch member for adjustment longitudinally and transversely of the table, and guide fingers on each guide bar.

3. In a printing press, a feeder table, a feeder bar extending overzthe table, a plurality of clamp members adjustable longitudinally of said feeder bar, and a guide for each clamp member adjustable transversely of said feeder bar. V

4. In a printing press, a feeder table, a feeder bar extending over thetable, a plurality of clamp members adjustable longi- NELS H. NELSON.
